As a builder I'm neutral on this one. I believe the reason that the access to heads is not allowed to normal players is due to abuse of it. Heads along with banners cause very bad lag problems within the server, so too many heads/banners in a chunk can cause TERRIBLE lag spikes and can make the area unusable at times. Basic heads such as computers or books. .whatever is helpful may be fine to give access to, but I see people covering and entire room with heads and banners and its just. .awful. If its such a big problem and this does get denied, my dms are always open to come give players heads if they need! :)
